scratch3-tello's Issues

Open exe without connecting to Tello

Hi, I noticed that in the documentation, The following was bolded:
After connecting to Tello, launch Scratch3-Tello.exe
I was wondering if there is anyway to open the exe without connecting to a Tello. This might be a duplicate of the discussion here. Would love to contribute if there some direction in your mind? Thanks for the excellent project!

Use with mission pads from DJI Tello EDU

I am just getting started with the DJI Tello. I have the EDU version that also includes some mission pads that can be detected by the sensor on the drone and uniquely identified by an integer number. There are some other commands available, described here: https://dl-cdn.ryzerobotics.com/downloads/Tello/Tello%20Mission%20Pad%20User%20Guide.pdf.

Would you consider adding these commands to the scratch extension?

node

sir i have this code run in my code my code in add extension tello3 drone in not solve earror node dgrame in telloprocessor please tell me solution about this earror quickly

Not working

Hello!
I tried to run Scratch Tello in three different computers, but with no success.
I also ran the clear command queue and also didn't work.
Could you give me any suggestion?

functional?

Hey @kebhr

I am so excited to see this repo. I would love to get students up and running with Tello and Scratch 3. Is the current build functional (sorry, I didn't see any details in the readme/etc.)?

Thanks much.
Andy

Repeating tello commands if tello fails to execute them

Dear Kanta Ebihara

Thank you for publishing your Scratch3 tello extension. It must have been a lot of work to figure out how to control the tello drone from scratch.

I use your scratch tello extension to teach programming at a primary school in the Netherlands. During the coding workshops, kids have to program some maneuvers or try to find and land on a mission pad automatically.

Sometimes my tello drones fails to perform a command at the first time. However, when I send the same command again a few seconds later, it is performed as expected. I have found a nice idea in this python library (https://github.com/damiafuentes/DJITelloPy): commands are repeated if tello fails the execute them.

I have tried to add repeating of tello commands to the scratch3 tello extension. Similar to the scratch "Wait X sec" block, the tello blocks are also waiting until tello confirms a command with "ok". If tello does not reply within 7-10sec or answers with an error message, then the command is sent again to the drone. The code makes use of the scratch util.yield() function, which ensures that the scratch even loop keeps on calling the code of the tello block, until it succeeds.

I thought, you might find the code interesting. Feel free to download it here:
scratch3_tello.zip

Please do not hesitate to reply if you have any comment or question on the code.

Best regards,
Andreas Zolnay

¿Bloque "flip" en extensión tello para Scratch 3.0?

Buenas tardes,
Me gustaría saber cómo codificar un vuelo de dron tipo "Flip" con los bloques que se cargan a través de la extensión tello añadida a Scratch Desktop. Gracias!

wrong behaviour

when I execute takeoff Tello takes off and starts drifting to the back right.
and it won't receive any other command.
then after some seconds, it starts blinking red and loose connection to scratch

How to get Scratch3-Tello with the Lego Boost estension

hi
I have an issue : i need to set up training for engineer with a combination of tello and a lego boost. I ahve seen that scratch3 includes the lego boost extension (but not the tello one) while the scratch desktop (based on scratch3) does not include the lego boost extension.
Is it normal? do I have to do something the get both extension ?
Thanks in advance for your answer. My objective is to set up a business cse with a recognition drone and a recovery car controlled by the same application.

Installation issues on Ubuntu

I'm a teacher in an association and I learn to code to children on Tello drone.

I have compile scratch3-tello on Ubuntu 21.04 on a raspberry pi and also on Lubuntu 20.04.3 on PC.
The result of this compilation is OK on the 2 platforms.
But when I launch scratch3-tello with "npm start", I obtain this 2 debug windows, same error messages in the console :

But I still can command Tello with Scratch.

And making the package with "npm run dist:dir" doesn't work :

The version of node and npm are the same in the 2 platforms :

Thanks for this good job kebhr

reconnect to tello without restarting scratch

Great to see that you developed this extension for the Tello for Scratch 3.0. However, I am looking for a way to have Scratch reconnect to the drone without having to restart the application every time. The connection is lost quite often with the batteries only supplying about 10 minutes of flying time (max).

Is there a way of doing this? Maybe by running a separate script in the background?

Drone command buffer acts weird

I can't say for sure if this is an issue with the drone itself or the version of the scratch 3 tello I am using, but putting fairly simple code like when I press right arrow, move some amount of distance to the right results in unintended outcomes. It takes off fine and I can press right arrow and it moves right, however because I pressed right for more than 1 frame and the drone takes more than 1 frame to move it just executes that command over and over and over and over until it hits a wall or it runs out of commands that have built up in the queue. I've tried using clear command queue but that seems to cause it to ignore a lot of commands. Perhaps it is an issue with how I am coding it and the scratch code has to be more complex, but all I really want to achieve as as follows: a pretty intuitive keyboard control that when you use arrow keys it moves the direction you press until you let go and is then able to respond to you pressing another direction pretty quickly. If that isn't possible due to limitations in the drone, then I understand.
